<span>The balance equation will be
234/91 Pa --> 234/92 U + </span>a beta particle
An example of it is potassium-40 nucleus. A beta particle has a high-energy and high-speed electron in the radioactive decay. These particles ranges <span> from 0 MeV to 4 MeV. It carry one charge only and it is positively charge, it is called positron.</span>
Answer:
The solution is 50 %wt
Explanation:
50% wt is a sort of concentration and means, that 50 g of solute (in this case, the potassium bromide) dissolved in 100 g of water.
It is the same to say, that there are 50g of KBr for every 100g of H₂O
Answer:
artic is correct please give brainliest please??
Answer:
d = 4.5 g/cm³
Metal cube is made up off titanium.
Explanation:
Given data:
Edge length of cube = a = 11.4 mm
Mass of metal cube = 6.67 g
Density and identity of metal = ?
Solution:
First of all we will calculate the volume of cube.
V = a³
V = (11.4mm)³
V = 1481.54 mm³
mm³ to cm³:
1481.54 mm³× 1 cm³/ 1000 mm³
1.482 cm³
Density:
d = m/v
d = 6.67 g/ 1.482 cm³
d = 4.5 g/cm³
Metal cube is made up off titanium because density of titanium is 4.5 g/cm³.
