They all belong to the Electromagnetic Spectrum.
Hope its right!!
Hope this helped too!!!!
The amount of heat required is calculated using the below formula
Q(heat) =M(mass) xC(specific heat capacity)x delta T (change in temperature)
change in the temperature in kelvin=(35+273)- (25 +2730= 10K
c= 2.48 j/g/k
mass= 54.0 g
Q= 54.0 g x 2.48 j/g/k x 10k = 1339.2 joules is required
Answer:
approx. 1.37 moles.
Explanation:
No. of moles = no. of given molecules/NA
No. of moles = 8.3 × 10^23 / 6.023 × 10^23
= 1.3780 moles
Answer:
The correct option is;
Chemical spill kit
Explanation:
When cleaning simple chemical spills that do not spread or indirectly put people and property in danger and does not negatively impact o the environment the risk, quantity and likely impact of the spill should be evaluated then with a chemical spill kit which comprises of personal protective clothing, materials that are absorbent, waste bags, broom and dustpan and a waste container can be used absorb, contain the residues, clean the spill and put the collected waste away.
