Answer:
D. Thermometer
Explanation:
The equipment used to measure the temperature of any reaction is the thermometer.
A thermometer is any device that has been specifically calibrated to measure the temperature values of reaction.
- Temperature is the degree of hotness or coldness of a body.
- Cold bodies have very low temperature.
- Hot bodies have high temperatures.
- There are different types of thermometers in use for various purposes.
Answer:
D. Reduction takes place at the cathode, which is negatively charged.
Explanation:
In an electrolytic cell there are two electrodes; the cathode and the anode. The anode is the positive electrode while the cathode is the negative electrode. Oxidation occurs at the anode while reduction occurs at the cathode.
At the anode, species give up electrons and become positively charged ions while at the cathode species accept electrons and become reduced.
Answer:
Atomic mass of Sodium is 22.9897 u. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10 -24 grams.
Explanation:
For bent molecular geometry<span> when the electron-pair geometry is trigonal </span>planar<span> the </span>bond angle<span> is slightly less than 120 degrees, around 118 degrees. </span>
I think the answer is true but I'm not very sure
