Strontium sulfide react with aqueus copper(ii) nitrate to form strontium (ii)nitrate and copper sulfide. the chemical equation is represented as follows
SrSO4(S) plus CU(NO3)2(aq) -->Sr(NO3)2(aq) PLUS CUSO4(s
the equation is balanced since both cupper and strontium have a valence of two.
The two main constituents of the sun, are both lightweight elements.
<h3 /><h3>What is constituents of the sun?</h3>
Helium and hydrogen make up the majority of the sun's mass (He). The sun is made up of 92.1% hydrogen and 7.9% helium by mass. Less than 0.1 percent of the mass of the sun is made up of different metals. The surface of the sun is around 10,340 degrees Fahrenheit hot (5,726 degrees Celsius).
The majority of the sun's emissions come from particles like neutrinos that travel beyond the light the sun's surface emits and can't be seen with ordinary spectroscopic instruments. As a result, to identify these particles, specialised equipment were needed, such as the Super Kamiokande (Kamioka Observatory, Japan), which has incredibly sensitive light sensors. These particles provided evidence that nuclear fusion processes were taking place in the Sun's core, which is what caused their emission.
