Answer:
Yes
Explanation:
As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level. This is what is meant by "thin air".
Answer:
Yes because the air becomes less compressed and is therefore thinner.
Explanation:
B. similar to other minerals
C. variable depending on where its found
D. influenced by heat and light
0.75 mole of H2CO3 = 47 g
3.42 moles CO = 95.8 g
4.1 moles Li2O = 94 g
Answer:
4.1 moles Li2O = 94 g (incorrect)
4.1 mole of Li2O = 122.6g(correct)
Explanation:
1. Molar mass of O2 = 32
0.2 mole of 32 = 0.2×32 = 6.4g (correct)
2. Molar mass of H2CO3 = 62.03
0.75 mole of 62.03 = 0.75×62.03 = 46.5g (47 is correct)
3. Molar mass of CO = 28
3.42 moles of 30 = 3.42×28 = 95.76 (95.8 is correct)
4. Molar mass of Li2O = 29.9
4.1 mole of Li2O = 4.1×29.9 = 122.59g (94g is incorrect)
Answer:
It's 4.1 moles Li2O = 94 g on Odyssey ware
I got you my friend.
mass = 42.3 kg
If you want step by step let me know in the comments and ill post a step by step in the comment section.
The law of mass conservation depicts that the mass of reactants is equal to the mass of products, so the mass of the candle is changed from solid state to gaseous state which have the same mass of the wasted candle.
According to the law of conservation of mass, it has been described that the mass neither formed nor destroyed, it can only transferred from one state to another state.
Due to changes in states of matter, the mass is only rearranged and changed, so during a chemical reaction, the mass of the reactants and the products are same in a closed reaction.
There for when burning the candle it only changes its state from solid to gaseous state that follow the law of conservation of mass.

well from my teacher when we did this experiment she said that I would most likely will violate it unless its covered up!
I really hope I helped thx!
Answer:
Energy is absorbed, so the mass is reduced
Explanation:
The relationship between the mass and the energy is given by Einstein formula as : m is the mass of an atom c is the speed of light When an atom is formed, the energy gets absorbed. As a result mass will decrease as per Einstein's equation.
So, the correct option is (c) "Energy is absorbed, so the mass is reduced".
