The periodic table is based on an element's

grin007 [14]

Well, TECHNICALLY, the periodic table is "based" upon a whole myriad of characteristics. But if you're talking about the consecutive arrangement of elements...it would be B, the atomic number.

Assume a density of water of 1.00 g/mL, and calculate the mass of water in the solution

tiny-mole [99]

Answer:

1g or 10^-3kg

Explanation:

as you know , the density =mass \volume

so you have the mass from the number it self

<h2> $\frac{1g}{1 ml}$ so from this equation, you will get 1 g and you can to SI to be $10^{-3}$ kg</h2>

Are frosted flakes healthier than fruit loops?

Komok [63]

Answer:

The answer is below!!

Explanation:

Although Frosted Flakes are higher in sugar than other cereals and often not considered diet food, they can be part of a healthy weight-loss plan. Cereals that are low in calories and fat content such as Frosted Flakes may help you lose weight.

“Froot Loops is an excellent source of many essential vitamins and minerals and it is also a good source of fiber with only 12 grams of sugar,” said Celeste A. Clark, senior vice president of global nutrition for Kellogg's, which makes Froot Loops.

A 3.4 g sample of sodium hydrogen carbonate is added to a solution of acetic acid weighing 10.9 g. The two substances react, rel

natima [27]

Answer: 2.7 grams

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

$NaHCO_3(aq)+CH_3COOH(aq)\rightarrow CH_3COONa(aq)+H_2O(l)+CO_2(g)$

Given: mass of sodium hydrogen carbonate = 3.4 g

mass of acetic acid = 10.9 g

Mass of reactants = mass of sodium hydrogen carbonate+ mass of acetic acid = 3.4 + 10.9= 14.3 g

Mass of reactants = Mass of products in reaction vessel + mass of carbon dioxide (as it escapes)

Mass of carbon dioxide = 14.3 - 11.6 =2.7 g

Thus the mass of carbon dioxide released during the reaction is 2.7 grams.
