Okay... what are the following
Answer:
A. Smaller, Larger
Explanation:
Every object that has mass obeys the Law of Universal Gravitation. Everything attracts everything else. The same gravity that keeps us down on the ground keeps planets in orbit. However, in space, the smaller object will feel the pull of the larger one much more strongly, which is why it will begin to orbit it
Answer:
0.385J/g°C
Explanation:
Using the following formula;
Q = m. c. ∆T
Where;
Q = amount of heat (joules)
m = mass of substance (g)
c = specific heat capacity (J/g°C)
∆T = change in temperature (°C)
According to the provided information in this question;
Q = 318 cal
1 calorie = 4.184J
318 cal = 318 × 4.184 = 1330.512J
m = 279g
∆T = 27.2°C - 14.8°C = 12.4°C
Hence, using Q = m. c. ∆T
c = Q ÷ (m. ∆T)
c = 1330.512 ÷ (279 × 12.4)
c = 1330.512 ÷ 3459.6
c = 0.385
Therefore, the specific heat of copper is 0.385J/g°C
Answer:
1A, 3B, and 7A are examples of group _ on the periodic table. ... Elements in group 2 are all called alkaline earth metals.
Explanation:
Answer:
We'll have 1.00 mol H2
Explanation:
Step 1: Data given
Number of moles of Mg = 1.00 moles
Step 2: The balanced equation
Mg(s) + H2SO4(aq) → MgSO4(aq) + H2(g)
Step 3: Calculate moles of H2
For 1 mol Mg we need 1 mol H2SO4 to produce 1 mol MgSO4 and 1 mol H2
We'll have 1.00 mol H2
