Answer: 0.85075J/g.K
Explanation:
Mass of the material = 100g
Energy (Q) = 5104.5J
T1 = 20°C = 293K
T2 = 80°C = 353K
Formula for heat energy (Q) = mc ∇T
Q = mc∇T
∇T = T2 - T1
∇T = 353K - 293K = 60K
Q = mc∇T
C = Q / m∇T
C = (5104.5) / (100 * 60)
C = 0.85075 J/gK
The specific heat capacity of the material is 0.85075J/gK.
Answer:
see below
Explanation:
16. 1 P₄(s) + 6 F₂(g) → 1 PF₃(s)
17. 2 C(s) + 2 H₂O(g) → 1 CH₄(g) + 1 CO₂(g)
18. 2 HgO(s)→ 1 O₂(g) + 2 Hg(l)
19. 1 CaCO₃(s) → 1 CO₂(g) + 1 CaO(s)
The molecule of mixture cannot be seen hence, it will be considered as homogeneous mixture.
<h3>
What is molecule?</h3>
A molecule is just a collection of more than two atoms bound together by chemical bonds; depending on the context, the phrase doesn't have to include ions that meet this requirement.
<h3>
What is homogeneous mixture?</h3>
Solids, liquids, as well as gases, can all be homogeneous mixtures. Through, they have almost the same look and chemical makeup.
When sugar will be dissolved, the sucrose molecules get separated from one another. The materials that make up individual molecules stay together like sucrose molecules sucrose molecules, so the molecule will not break up.
Therefore mixture can be considered as molecule and homogeneous mixture.

Answer: law of conservation of matter states that mass in an isolated system can neither be created nor destroyed by chemical reactions or physical transformation.
thus, the mass of the reactants in a reaction must be equal to the mass of the products
