Guys please I need an answer for this asap
mina [271]
I need more information, there are meant to be coefficients in front of one of those ..

but you’d put .2 over the coefficients, and if there is not one, you put an X. then you will cross multiply, and divide if you have 2x or something greater than X.

Why would someone need to find the relative density of an object?
Ede4ka [16]

Answer:

The relative densities of an object and the liquid it is placed in determine whether that object will sink or float. An object that has a higher density than the liquid it's in will sink. An object that has a lower density than the liquid it's in will float.

Explanation:

Hope it helps!

Why does dark chocolate melt faster in the sun?<br><br> Claim<br><br> Evidence <br><br> Reasoning
anastassius [24]

Explanation:

The reason as to why the dark chocolate always melted the fastest was because of it's colour. It was a darker shade than the milk and white chocolate and the sun naturally absorbs dark colours therefore it melted faster.

Four atoms are arbitrarily labeled D, E, F, and G. Their electronegativities are as follows: D = 3.8, E = 3.3, F = 2.8, and G =
PSYCHO15rus [73]

Answer:

Thus the order of covalent character will be

DG < EG < DF < DE

Explanation:

The electronegativity decides the nature of bond formed between two atoms.

More the difference in electronegativity more the ionic character in the bond formed.

Let us check the electronegativity difference between the elements forming molecules

a) DE :

3.8-3.3 = 0.5

b) DG :

3.8-1.3 = 2.5

c) EG

3.3-1.3 = 2

d) DF

3.8-2.8 = 1.3

So the maximum ionic character will be in DG and minimum in DE

Thus the order of covalent character will be

DG < EG < DF < DE
