Answer : The temperature in Kelvin is, 290 K
Explanation :
S.I : It is known as the international System of Units. It is defined as a scientific method to express the magnitude of the several basics units.
There are seven basic units in the system from which the other units are derived.
The seven base unit are, meter for length, kilogram for mass, second for time, ampere for current, kelvin for temperature, mole for amount of substance and candela for intensity.
The conversion used for the temperature from degree Celsius to Kelvin is:
where,
= temperature in Kelvin
= temperature in centigrade
As we are given the temperature in degree Celsius is, 17
Now we have to determine the temperature in Kelvin.
Therefore, the temperature in Kelvin is, 290 K
Answer:
% yield = (0.872 g Cu / 1.017 g ) x 100 = 85.74 %.
A covalent bond is formed between two non-metals that have similar electronegativities.
An <em>i</em><em>o</em><em>n</em><em>i</em><em>c</em><em> </em><em>b</em><em>o</em><em>n</em><em>d</em> is formed between a metal and a non-metal. Non-metals(-ve ion) are "stronger" than the metal(+ve ion) and can get electrons very easily from the metal. These two opposite ions attract each other and form the ionic bond.
Answer:
200.6cm³
Explanation:
Using Charles law equation as follows:
V1/T1 = V2/T2
Where;
V1 = initial volume (cm³)
V2 = final volume (cm³)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the question;
initial volume (V1) = 254cm³
final volume (V2) = ?
Initial temperature (T1) = 72.6°C = 72.6 + 273 = 345.6K
Final temperature (T2) = 273K
V1/T1 = V2/T2
254/345.6 = V2/273
Cross multiply
345.6 × V2 = 273 × 254
345.6V2 = 69342
V2 = 69342 ÷ 345.6
V2 = 200.6cm³
The force acting between two charged particles A and B is 5.2 x 105 newtons. Charges A and B are 2.4 x 102 meters apart. If the charge on particle A is 7.2 x 108 coulombs, what is the charge of particle B? (k 7 9.0 x 109 newton meters?/coulomb)
