Answer:
1: plastic are poor conductor BC oz they allow heat to pass through
Answer:
The correct answer is 6.31 M
Explanation:
The molecular weight (MM) of NaOH is calculated as follows:
MM(NaOH) = Molar mass Na + Molar mass O + Molar mass H
= 23 g/mol + 16 g/mol + 1 g/mol
= 40 g/mol
We need the MM to convert from grams to moles. The molarity (moles of solute per liter of solution, in mol/L) can be calculated by dividing the mass into the volume in liters (195 ml = 0.195 L) and then multiplying by the MM as follows:
M = 49.24 g/0.195 L x 1 mol/40 g = 6.31 mol/L = 6.31 M
Answer: A. Gamma Ray
Explanation:
X-ray scans can diagnose possibly life-threatening conditions such as blocked blood vessels, bone cancer, and infections. However, x-rays produce ionizing radiation—a form of radiation that has the potential to harm living tissue. However, the risk of developing cancer from radiation exposure is generally small.
