Answer is: the specific heat capacity of the metal is <span>A) 0.129 J/gK.
</span>m(metal) = 15,1 g.
Q = 48,75 J.
ΔT = 25 K.
Q = C · ΔT · m(metal).
C = Q ÷ ΔT · m(metal).
C = 48,75 J ÷ 25 K · 15,1 g.
C = 0,129 J/g·K.
A true most cases are parental abuse
Answer:
The answer to your question is: B
Explanation:
Physical properties are properties that occurs in matter but there is not change in the composition.
A. Solid ice can be very brittle. This is a physical property.
B. Water can form hydrogen and oxygen gas under electrolysis conditions. Here there is a change in the composition of matter, this is an example of chemical property
C. Water can freeze solid at 32 degrees Fahrenheit.
This is a physical property.
D. Liquid water can turn into steam in a heated tea kettle. This is a physical property
E. none of the above This option is wrong because option B is correct.
To know if an equation is balanced you need to check and see how much of each molecule is on either side of the arrow. Right now you have 1-Ca, 2-H, 2-Cl on the left side of the arrow and 1-Ca, 2-Cl, and 2-H on the right side too. Because all the molecules are equal on both sides this means that the equation is balanced. So in front of the CaCl2 there is an assumed coefficient of 1. The answer is 1.
14) gas to liquid to solid
15)chlorine displaces bromine from potassium bromide
16) non-metals
6)vertical
7)similar properties
8)there are patterns
10)decrease
11)very reactive
12) hydrogen
18)lower density than air
19)better insulator
20)metalloids
