B. Low; very little
Explanation:
Metals such as iron, lead, copper and zinc have low specific heats. This means that it takes very little energy to change their temperature.
Specific heat is the heat required to raise the temperature of 1g of substance by 1°C.
Metals have good thermal conductivity and generally have low specific heat. This implies that their temperature can easily be raised when heated.
Some substances like water have very high specific heat. This suggests that they require more heat to raise their temperature.

Answer:
The Moon gets its light from the Sun. In the same way that the Sun illuminates Earth, the Moon reflects the Sun's light, making it appear bright in our sky. Have your child hold the fruit at arm's length, pointing at the light.

Answer:
Explanation:
6.90 mol x grams
2As + 6NaOH = 2Na3AsO3 + 3H2
6 mol 2 mol
192 g/mol
6.90 mol NaOH x 2 mol Na3AsO3/6 mol NaOH== 2.3 mol Na3AsO3
2.3 mol Na3AsO3 x 192 g/mol = 442 g Na3AsO3
Answer:
Rubidium
Explanation:
Add the exponents: 2+2+6+2+6+2+10+6+1=37
Look for the atomic number 37
Answer:
3.87 x 10^24
Explanation:
Simply multiply the moles by avogadros number
6.42 moles of H2O x 6.022 x 10^23 molecules/1 mole of H2O = 3.87 x 10^24 molecules of H2O
