Answer:-
500324 grams
Explanation:-
Heat absorbed Q = M x Cp x T
We are given T = 10 [ The maximum allowed temperature increase]
Plugging in the values
6.70 x 10^ 6 J = M x 30.8 J / (K mol) x 10 K
M = 6.70 x 10 ^6 / (30.8 x 10)
= 21753 moles
Atomic Mass of sodium =23 gram / mol
Grams of liquid sodium required = 21753 moles x 23 grams / mol
= 500324 grams
Answer:
moon's motion without gravity
Explanation:
The reason it's moon's motion without gravity is because if you take away earths gravitational pull it would simply go in the direction it last was, and the last direction it was, was where the dotted arrow is.
Answer: :)
Explanation:
In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom
Answer:
Compound
Explanation:
We want to know if it's a compound or a mixture.
An example of a mixture is salt water: you can heat it hot enough to boil off the water, leaving only the salt. This is a physical change, which is how you know it's a mixture.
Something like gold is a compound: if you heat it, or hit it, you'll still only have gold. You can only break it down by chemical means, which is how you know it's a compound.
I really don’t know if I don’t have more information
