Which explains the law of conservation of mass?

In 1986, there was an accident that led to an explosion at the Chernobyl Power Plant in what was then the Soviet Union. Soon aft

Nadya [2.5K]

Answer:

Radium (Ra)

Explanation:

The nuclear fuel at Chernobyl was uranium-235. However, one of the decay products of uranium-235 is radium.

Radium is chemically similar to calcium since it has two valence electrons and is the heaviest and last member of group 2.

Owing to its chemical similarity to calcium, it was able to replace calcium in people's teeth and bones. Radium is radioactive, the half life of Ra-226 is about 1602 years.

Other elements of group 2 are; beryllium, magnesium, strontium and barium.

Which atoms has the same numbers of protons and neutrons

Luda [366]

Explanation:

Generally, the light nuclei atoms have the same number of protons and neutrons in the nuclear composition. They have a proton to neutrons ratio of almost or equal to 1 because in such a way the nucleus can achieve stability.

What is causing the global average temperature on earth to increase

Serggg [28]

Increase in greenhouse gas emission

Explanation:

Global average temperature of the earth is increasing due to a surge in the amount of greenhouse gases being emitted.

The major greenhouse gas is carbon dioxide.

This gas is produced by a wide range of industrial processes and combustion of fuels in automobiles.

Anomalous concentration of this gas in the atmosphere leads to an increase in earth's temperature.

These gases interacts with long wave radiation produced by the earth and prevents them from escaping. In turn, they warm the earth and keep it at fairly uniform temperature.

When these gases are too much in concentration they lead to an anomalous increase in temperature.
