Answer:

28.05316 grams

Explanation:

Temperature of gas at volume of 950 cm³ is 368.14K or 94.99⁰c.

Given,

in this question, volume occupied by gas at 10.9⁰c is 733cm³.

we have to find out temperature at which gas occupies volume of 950 cm³.

First, convert temperature from celcius to Kelvin

10.9⁰c = 10.9 + 273.15 = 284.05 K

By equation or Boyle's Law

P1 x V1 / T1 = P2 x V2 / T2

Pressure is constant here

therefore, V1 / T1 = V2 / T2

here, V1 = 733 cm³

T1 = 284.05 K

V2 = 950 cm³

we have to find out T2

So, 733 / 284.05 = 950 / T2

T2 = 284.05 × 950 / 733 = 368.14 K

= 94. 99⁰c

Therefore the temperature of gas at volume of 950 cm³ is 368.14K or 94.99⁰c.

Answer:

True

Explanation:

A polyribosome (or polysome) is a complex of one mRNA molecule and two or more ribosomes that  form a polypeptide chain during active translation. Since multiple ribosomes can translate  mRNA simultaneously, many polypeptides can be produced simultaneously from a single mRNA.

1. mRNA: contains the codon

2. tRNA : contains the anticodon for the mRNA

3. Ribosome (large & small subunits): facilitates interaction between mRNA and tRNA

4. Amino acids:

5. Initation Factors: proteins important in the interaction/binding of the small subunit, mRNA, TRNAmet, and the Shine Dalgarno sequence

7. Elongation Factors: bring charged tRNA's to the A site of the ribosome

8. GTP: provides energy

Ribosome recruitment in eukaryotes occurs when the eukaryotic initiation factor e1F4F and poly(A) binding protein (PABP) recognize 5′-capped mRNAs and recruit the 43S ribosome complex to this site. increase. In addition, the Kozak consensus sequence ACCAUGG is also required for translation initiation. Therefore, at first glance, it seems unlikely that  overlapping sequences will be translated.

Explanation:

sn1 reactions where there is only one stereocenter and the leaving group is attached to that stereocenter will produce racemization products.

A stereocenter, also known as a stereogenic centre, is an atom-bearing group in which the interaction of any two groups results in the formation of a stereoisomer. Although the most common cause of chirality, the presence of a stereocenter is not necessary for chirality in a molecule. Geometrically speaking, a stereocenter is a point (position) in a molecule; it is frequently an atom called carbon, but this is not always the case.

An optically active substance is transformed into a racemic form through racemization, which can occur through heat or a chemical process. A-racemic mixture is the term used for the resultant 1:1 molar ratio of enantiomers. Racemization can happen by a variety of processes, and it is particularly important in pharmacology since various enantiomers may have different medical consequences.

One of the postulates of Dalton's atomic theory is that "All matter is made of atoms, which are indivisible and indestructible."

Everything in the universe is made up of small, indivisible particles called atoms. These atoms cannot be broken down into smaller pieces and they cannot be destroyed. This postulate is important because it helps us understand the basic building blocks of matter and how they behave.

Atoms can be combined in simple integer ratios to form compounds, and during a chemical reaction, atoms are rearranged but not created or destroyed. This postulate is known as the law of conservation of mass. Without atoms, there would be no matter and therefore no universe as we know it.

The approximate balance in the account at the end of 6 years is $159,074. Rounded to the nearest dollar, it is $159,074.

Assuming that the annual rate of $20,000 is deposited at the beginning of each year, the total amount deposited over 6 years would be $120,000. With continuous compounding at 5% interest rate, the formula to calculate the balance in the account after 6 years is:
A = Pe^(rt)
Where A is the balance, P is the principal (amount deposited), e is the mathematical constant approximately equal to 2.71828, r is the interest rate in decimal form, and t is the time in years.
Plugging in the values, we get:
A = $120,000e^(0.05*6)
A = $159,073.51
Therefore, the approximate balance in the account at the end of 6 years is $159,074. Rounded to the nearest dollar, it is $159,074.

Answer:

True

Explanation:

One mole of CaCl₂contains 2 moles of chloride ions.

Calcium chloride (CaCl₂) is a salt that consists of one calcium ion (Ca2+) and two chloride ions (Cl-). Therefore, one mole of CaCl₂ contains two moles of chloride ions (2 Cl-).

To calculate the number of moles of Cl- in one mole of CaCl₂, we can use the formula:

moles of Cl- = 2 x moles of CaCl₂

Since one mole of CaCl₂ contains 1 mol of calcium ion and 2 moles of chloride ions, the total number of moles in one mole of CaCl₂is:

1 + 2 = 3 moles

So, the number of moles of Cl- in one mole of CaCl₂ is:

moles of Cl- = 2 x moles of CaCl₂ = 2 x 1 = 2 moles

Therefore, one mole ofCaCl₂ contains 2 moles of chloride ions.

The statement "Throwing overweight and underweight balls will help the pitcher gain strength in their arm" is an inaccurate explanation for this training.

Overweight and underweight balls balls may help a pitcher generate more velocity, but they will not necessarily make them more accurate which in fact, throwing weighted balls can be detrimental to a pitcher's accuracy because the ball has a different center of gravity than a standard regulation ball. This can cause the ball to travel in unexpected directions when the pitcher releases it. Furthermore, throwing weighted balls can also lead to arm fatigue, which can in turn lead to a decrease in accuracy. Therefore, while weighted balls can be used to increase velocity, they will not necessarily make a pitcher more accurate.

The given reaction is already balanced, that is to say tha the number of atoms in the reactants matches the number of atoms in the products. In the reaction, we can see the relationship between CaC2 and H2O. For each mole of CaC2 two moles of H2O react.

So, if 4.8 moles of CaC2 are consumed the moles of H2O needed will be:

Mol of H2O = Mol of CaC2 x 2

Mol of H2O = 4.8 x 2 = 9.6 mol of H2O

Now, to calculate the grams of H2O we will use the following equation and the mass molar of H2O.

Mass molar of H2O =18.01 g/mol

So, if 4.8 moles of CaC2 are consumed in this reaction, 172.9 g of H2O are needed

If the body could not adapt to these changes, we wouldn't be able to live all over the planet; from the equator up to the polar caps.

The difference in degrees Fahrenheit between the maximum expected temperatures by the end of the century between the lower and higher emissions scenarios can vary depending on various factors and assumptions.

However, in general, the lower emissions scenario is expected to result in a lower increase in global temperatures compared to the higher emissions scenario.

This means that the maximum expected temperature rise by the end of the century under the lower emissions scenario would be lower than that of the higher emissions scenario.
