Answer:

8.467 grams of oxygen

Explanation:

The law governing this problem is "The Law of Constant Composition "

As per this law, all compounds irrespective of their origin and source have the same composition and properties  in their purest form

It is a simple proportion and ratio related problem.

1.50 grams of carbon require 2.0 grams of oxygen

1.0 grams of carbon will require oxygen

= \frac{2}{1.5}

6.35 grams of carbon will require oxygen

\frac{2}{1.5}*6.35\\= 8.4666\\= 8.467

 It contain oxygen atom calculated below
<span>6.35gC x 2.00gO/1.50gC
 = 8.47g O 
</span><span>  The law is that a sample of a pure substance is the same as any other sample of the pure substance no matter what the source is

Answer:

c. Two sister chromatids did not separate into the proper daughter cells during anaphase.

Explanation:

The observed cell is undergoing mitosis which does not include separation of homologous chromosomes. During anaphase of mitosis, two sister chromatids of each chromosome separate from each other. They move to opposite poles. This results in equal distribution of two complete sets of chromosomes to each daughter cell.

However, the failure of two sister chromatids of a chromosome during anaphase would lead to the formation of two abnormal daughter cells. One of the daughter cells would have one extra chromosome (2n+1) while the other would lack one chromosome from the diploid set (2n-1).

Why shouldn't you have more than one<br> independent variable
quester [9]
There are often not more than one or two independent variables tested in an experiment, otherwise it is difficult to determine the influence of each upon the final results. There may be several dependent variables, because manipulating the independent variable can influence many different things.

If a meal supplies 110 g of carbohydrates, 25 g of protein, 20 g of fat, and the equivalent of 5 g of alcohol, what % of the kca
mars1129 [50]

Answer:

0.058 % kcalories comes from carbohydrate.

Explanation:

1 g of carbohydrtes gives 4 calories, 1 g of protein gives 4 kcalories, 1 gm of fat gives 9 calories and 1 g of alcohol gives 7 calories of energy.

Thus in a meal  that contains 110 g carbohydrates gives 110 x 4 = 440 calories,  25 g protein gives 25 x 4 = 100 calories, 20 g fat gives 20 x 9 = 180 calories and 5 g alcohol gives 5 x 7 =  35 calories.

Total calories in a meal  440+100+180+35 = 755.

Therefore % of carbogydrate will be 440x 100 divided by 755 = 58.27 %

In kcalories % would be 58.27/1000 = 0.5827 %
