Answer:
I think it's thermochemical reaction and sorry if it's wrong
Answer:
The correct answer would be "They could allow scientists to explore remote places, like other planets, in new ways".
As the artificial muscles are lightweight and can withstand high temperatures they can be used efficiently in exploring remote places, stars, or planets where humans can not survive.
For example, they can be used to explore the inner or outer core region of the earth which would help us more in understanding the earth.
Similarly, robots with these types of muscles can be used to obtain samples from other planets which have a very high temperature such as mercury.
The answer is b: in the oscillating electric and magnetic fields
Answer:
50.00 g of NO
Explanation:
Remember that the balanced chemical reaction equation is indispensable in solving any question that has to do with stoichiometry. Hence the first step in solving the problem is noting down the balanced chemical reaction equation.
2NO(g) + O2 (g)→ 2NO2(g)
Now we try to find out the reactant in excess. The reactant in excess gives the greater mass of product.
For O2;
From the balanced reaction equation;
32 g of O2 yields 92g of NO2
16.00g of O2 will yield 16.00×92/32 = 46g of NO2
For NO;
30g of NO yields 92g of NO2
80.00 g of NO yields 80.00 × 92/30 = 245.33 g of NO2
Hence NO is the reactant in excess.
If 1 mole of O2 reacts with 2 moles of NO2 according to the balanced reaction equation
Then 32 g of O2 reacts with 60g of NO according to the balanced reaction equation
16.00 g of O2 reacts with 16.00 × 60 /32 = 30 g of NO
Hence mass of excess reactant used in the reaction = total mass of NO- mass of NO reacted= 80.00g -30.00g = 50.00 g of NO
Hence the mass of excess reactant used in the reaction is 50.00 g of NO
