Viewed as the focal science chemistry , Science chemistry includes the investigation of how various substances change tones, shape, size and structures when responded with one more material or a bunch of substances. Besides, the utilization of different Parts of Science across various fields has prompted numerous disclosures and very good quality advancements which has helped humanity in either way. Understanding Science in day to day existence is significant in light of the fact that:

The food we eat, the beauty care products we use or the medications we take, these go through substance responses.

It can assist you with settling on choices connected with a great many things like watering plants in view of seasons, setting the temperature to prepare a cake, picking the right medication for causticity, applying a specific SPF sunscreen, and so on.

It assists you with understanding which component your body needs more. For example, some might require Vitamin D more than others

**98 POINTS** Given 1.00 gram of (NH4)2 CO3, how many grams of this sample would be due to hydrogen?

Answers

OP already did it - CONGRATS!!

here are the steps 2 get the same ans:

(NH4)2 CO3 has 2x N, 8x H, 1x C and 3x O per molecule

so its molecular mass = 2x14 + 8x1 + 1x12 + 3x16

=28+8+12+48

=96g

of that 96g, 8x1=8g is due to Hydrogen

so by ratio n proportion, 1.00g will have 1x8/96 = 1/12g = 0.083g of H

What is the percent composition by mass of hydrogen in NH4HCO3 (gram-formula mass = 79 grams/mole)?

Answers

Answer:The percent composition by mass of hydrogen in $NH_4HCO_3$ is 6.32 %.

Explanation:

Molecular mass of the $NH_4HCO_3$ = 79 g/mol

Mass of the hydrogen atom present in one formula unit of $NH_4HCO_3$ :

$= 5* \text{(atomic mass of hydrogen)}=5* 1 g/mol= 5 g/mol}$

$\text{percentage of hydrogen}=\frac{\text{mass of the hydrogen in}NH_4HCO_3}{\text{molar mass of}NH_4HCO_3}* 100$

$\text{percentage of hydrogen}=(5g/mol)/(79 g/mol)* 100=6.32\%$

The percent composition by mass of hydrogen in $NH_4HCO_3$ is 6.32 %.

Answers: 6.3%

Based on your findings, which theory about alien thickness seems most valid or most accurate?

Answers

Answer:

C.) Alien thickness is mainly affected by temperature. The greater thickness at lower temperatures may be used as a way to stay warmer in colder weather.

Explanation:

Environmental systems.

Well aliens are like mysteries on Sci-Fi. Aliens aren't humans or just beings that are different from us. When you're saying the thickness, I am assuming about the body of the alien is full of hard and rusty skin that is not like ours.
