0.208 is the specific heat capacity of the metal.
Explanation:
Given:
mass (m) = 63.5 grams 0R 0.0635 kg
Heat absorbed (q) = 355 Joules
Δ T (change in temperature) = 4.56 degrees or 273.15+4.56 = 268.59 K
cp (specific heat capacity) = ?
the formula used for heat absorbed and to calculate specific heat capacity of a substance will be calculated by using the equation:
q = mc Δ T
c = 
c = 
= 0.208 J/gm K
specific heat capacity of 0.208 J/gm K
The specific heat capacity is defined as the heat required to raise the temperature of a substance which is 1 gram. The temperature is in Kelvin and energy required is in joules.
Answer:
d. it does all of that and even harms humans to some extent
let me know if its right
The atomic number of Be is 4, and so it has 2 shells. There are valence electrons in the second, which is the outermost, shell of Be. To get the element with one more shell, there would be 3 shells on the new element, and 1 less valence electron, so the new element should have 1 valence electron. Sodium is the element with 3 shells, and one valence electron which fits perfectly into the description.
Answer:
Option 1. 0.55 mol of C₄H₁₀
Explanation:
The reaction is:
2C₄H₁₀ + 13O₂ → 8 CO₂ + 10H₂O
This is a combustion reaction where carbon dioxide and water are produced.
We convert mass of produced water to moles → 50 g / 18 g/mol = 2.78 moles of water.
The stoichometry states that:
10 moles of water are made by 2 moles of C₄H₁₀
Therefore 2.78 moles of water will be made by (2.78 . 2) / 10 = 0.55 mol of C₄H₁₀
