<u>Answer:</u> The other isotope is
<u>Explanation:</u>
Beta decay is defined as the decay process in which a neutron gets converted to a proton and an electron.
In this decay process, beta particle is emitted. The emitted particle carries a charge of -1 units and has a mass of 0 units. The released beta particle is also known as electron.
The general equation for the beta decay process follows:
The chemical equation for the beta decay of an isotope that produces Sr-87 isotope follows:
The isotope that undergoes beta decay to form Strontium-87 isotope is Rubidium-87
Hence, the other isotope is
Answer : (C) 854.46 KPa.
Solution : Given,
Initial pressure = 400 KPa
Initial temperature = 110 K
Final temperature = 235 K
According to the Gay-Lussac's law, the absolute pressure is directly proportional to the absolute temperature at constant volume of an ideal gas.
P ∝ T
Formula used :
where,
= initial pressure
= final pressure
= initial temperature
= final temperature
Now put all the values in above formula, we get
By rearranging the terms, we get the value of new/final pressure.
= 854.5454 KPa 854.55 KPa
Answer:
Ionic bond
Explanation:
This type of chemical bond is called an ionic bond because the bond formed between two ions of opposite charge. The sodium cation (Na+) and the chlorine anion (Cl-) are attracted to one another to form sodium chloride, or table salt.
Answer: The specific heat capacity of metal is
Explanation:
As we know that,
where,
= mass of metal = 35 g
= mass of water = 220 g
= final temperature =
= temperature of metal =
= temperature of water =
= specific heat of metal = ?
= specific heat of water =
Now put all the given values in equation (1), we get
Therefore, the specific heat capacity of metal is
