Answer:
0.3832
Explanation:
Givens
m = 437.2 grams
c = ?
delta t = 69.8 - 19.3
H = 8460 J
Formula
H = m*c*Δt
Solution
8460 = 437.2 * c * (69.8 - 19.3)
8460 = 437.2 * c * 50.5
8460 = 22078.6 * c
c = 8460 / 22078,6
c = .3832 J / (oC * gr)
Answer:
Molarity= 0.071M
Explanation:
Molar mass of NaNO3= 23+14+(16*3)=85
n= m/M = 30/85= 0.353mol
V= 5L
Applying
n= CV
0.353= C×5
Simplify
C= 0.071M
Answer:
Bases taste bitter, feel slippery, and conduct electricity when dissolved in water. Indicator compounds such as litmus can be used to detect bases. Bases turn red litmus paper blue. The strength of bases is measured on the pH scale.
