Answer:
Chemical I would assume.
Explanation:
This is because drugs have chemicals in them.
The answer would be
C) To reduce destruction by providing early warning of severe weather
This can help us because then we can plan our day-to-day activities better and can definitely help keep us out of danger.
Answer:
According to IUPAC(international union of pure and applied chemistry)
Explanation:
there are four upcoming new element they are
.nihonium
.mascovium
.tennessine
.oganesson
When the amount of heat gained = the amount of heat loss
so, M*C*ΔTloses = M*C* ΔT gained
when here the water is gained heat as the Ti = 25°C and Tf= 28°C so it gains more heat.
∴( M * C * ΔT )W = (M*C*ΔT) Al
when Mw is the mass of water = 100 g
and C the specific heat capacity of water = 4.18
and ΔT the change in temperature for water= 28-25 = 3 ° C
and ΔT the change in temperature for Al = 100-28= 72°C
and M Al is the mass of Al block
C is the specific heat capacity of the block = 0.9
so by substitution:
100 g * 4.18*3 = M Al * 0.9*72
∴ the mass of Al block is = 100 g *4.18 / 0.9*72
= 19.35 g
Answer:
Cobaltous Nitride,I think so anyway.......
