Ocean water freezes just like freshwater, but at Lower temperature. Fresh water freezes At 32°F but see water freezes at about 28.4°F because of the salt in it it can be melted down to use as drinking water
as a heterogeneous mixture
Explanation:
because I just know that it is
Answer:
D. period is reciprocal of frequency.
Explanation:
<span>[Ar]4s²3d¹⁰4p⁴
We see that the last level is this element is 4, so this element should be in
4th period, it has 4 p-electrons, so it should be in 16th group.
4th period, 16th group - it is Se.
You can also go to the next element after Ar, and count beginning of this element 16. (2+10+4 =16 electrons)
From "K" (where K is the first) you count to 16 and it is going to be Se.</span>
According to the gas law, the relationship between the temperature and pressure is P1/T1=P2/T2. And the temperature is in the unit of K. So, P2=325*323/283=370.8 kPa.
