Answer:
3*10⁹ + 5.3*10¹⁰ = 5.6*10¹⁰
Explanation:
The values are given as exponents:
3*10⁹ and 5.3*10¹⁰
As per the rules:
-Before adding two numbers, all exponents must be the same
-The addition takes place between the numerical portion of the numbers
- The final value is rounded off to the least places in the decimal portion of the given numbers
Therefore, the two numbers to be added are:
Rounded off the final value to 1 decimal place gives:
5.6*10¹⁰
The final temperature of the gas is 260.01 K.
The final temperature can be calculated by using the equation as follows:-
........(1)
Here, and is the pressure of this gas before and after the changes.
and is volume of this gas before and after the changes.
and is the temperature (in degrees Kelvins) of this gas before and after the changes.
Given values:-
Substitute all the values in the equation (1) as follows:-
Hence, the final temperature of the gas is 260.60 K.
To know more about:-
Explanation:
The data is given as follows.
= 1.12 atm, = 1.67 atm
,
, = ?
Therefore, calculate the final temperature using the relation as follows.
=
=
=
= 260.605 K
= 260.61 K (approx)
Thus, we can conclude that final temperature is 260.61 K.
What is involved in redox reactions
A.the transfer of electrons between reactants
B.the bonding of ions to form chemical compounds
C.the addition of water to break down food macromolecules
D.the breaking down of water into hydrogen and oxygen atoms
Answer:
A
Explanation:
Redox reactions are comprised of two parts, a reduced half and an oxidized half, that always occur together. The reduced half gains electrons and the oxidation number decreases, while the oxidized half loses electrons and the oxidation number increases.
