Answer:
metal atoms lose electrons to form positive ions (cations)
Explanation:
metal atoms lose electrons to form positive ions (cations ) non-metal atoms gain electrons to form negative ions (anions )
Answer : The volume of liquid is 420 mL.
Explanation :
Density : The mass per unit volume of a substance is known as density.
Formula used:
![\text{Density}=\frac{\text{Mass}}{\text{Volume}}](https://tex.z-dn.net/?f=%5Ctext%7BDensity%7D%3D%5Cfrac%7B%5Ctext%7BMass%7D%7D%7B%5Ctext%7BVolume%7D%7D)
As we are given:
Density of mercury = 13.5 g/mL
Mass = 12.5 pounds
First we have to convert mass of sample from pound to gram.
Conversion used:
As, 1 pound = 453.6 g
So, 12.5 pounds = 453.6 × 12.5 g = 5670 g
Now we have to calculate the volume of liquid.
![\text{Density}=\frac{\text{Mass}}{\text{Volume}}](https://tex.z-dn.net/?f=%5Ctext%7BDensity%7D%3D%5Cfrac%7B%5Ctext%7BMass%7D%7D%7B%5Ctext%7BVolume%7D%7D)
Now putting all the given values in this formula, we get:
![13.5g/mL=\frac{5670g}{\text{Volume}}](https://tex.z-dn.net/?f=13.5g%2FmL%3D%5Cfrac%7B5670g%7D%7B%5Ctext%7BVolume%7D%7D)
Volume = 420 mL
Therefore, the volume of liquid is 420 mL.
Answer:
B
Explanation:
The sun can be dangerous but it also helps our Earth in a lot of ways
The answer is (4) synthesis. Synthesis reaction means that two or more reactants combine directly to one production. Substitution or single replacement means that one element of a compound is replaced by another element. Double replacement means that two ionic reactants exchange ions to form two new productions.
