Answer:
The correct option is;
a) The resulting mixture was cloudy
Explanation:
Here we have the initial color as
1. Colorless and
2. Dark blue
We analyze each of the results as follows
a) The resulting mixture was cloudy
A cloudy mixture forming when the two liquids are mixed is most likely due to the formation of a suspension from a new substance That is a new compound is formed
b) The total volume of the mixture was equal to the sum of the initial volumes.
Here since there is no change in the physical properties as the volume of the mixture is the sum of the volumes of the constituent then there is unlikely to be a chemical change
c) The resulting liquid was light blue
Here, the observation is more of a physical change
d) The liquids formed two separate layers in the beaker.
This is an indication that there was no mixing of the liquids hence no reaction or chemical change.
Correct answer choice is :
B) Chemistry
Explanation:
Advanced titanium-based compounds have been also used for some years for extremely stressed femoral segment stalks. Both metal samples present a higher impedance to pitting, crack, and galvanic corrosion, stress corrosion weakening and corrosion burnout than polished stainless steel of comparatively low power properties. For this purpose, the low element power of hip prostheses made of the recent stuff is paid for by a larger cross-section of the prosthetic stem, this depending on the geometric situations of the femur.
Answer:
30.0g CaCl2
Explanation:
20.0g Ca(OH)2=0.270mol
(0.270mol)(111.0g/mol)=30.0g CaCl2
The outer core is not under enough pressure to be a solid so it is liquid
The amount of heat (in calories) needed to raise the temperature is 324.885 calories
<h3>How to determine the temperature change </h3>
We'll begin by obtaining the temperature change. This can be obtained as followed:
- Initial temperature (T₁) = 14 °C
- Final temperature (T₂) = 25 °C
- Change in temperature (ΔT) = ?
ΔT = T₂ - T₁
ΔT = 25 - 14
ΔT = 11 °C
<h3>How to determine the heat (in Calories)</h3>
The amount of heat needed to raise the temperature can bee obtaimedals follow:
- Mass (M) = 33 g
- Change in temperature (ΔT) = 11 °C
- Specific heat capacity (C) of diethyl ether = 0.895 cal/g°C
- Heat (Q) =?
Q = MCΔT
Q = 33 × 0.895 × 11
Q = 324.885 calories
Thus, the amount of heat needed is 324.885 calories
