The answer is C due to the rain making contact with the iron it creates moisture which cause the iron to begin oxidizing which causes the iron to rust which is a chemical reaction then the blade which was once malleable because it was heat becomes harden and rust is created as I said before the physical aspect of the iron chances due to rust developing on it it's no longer has the luster it once had
Answer:
"The five factors are: the latitude zone, the elevation of the land, topography (landforms), ocean currents and winds."
Explanation:
1. The reaction is exothermic.
2. I know this because the delta H is a negative number. (-802.4 kJ)
3. This means that this reaction releases heat.
A. The gravitational force of the sun increased.
The gravitational pull increases as the mass increases
Answer:
The mass of titanium displaces 68.6 mL of water is 309.4 g.
Explanation:
Given that:-
Also, 1
= 1 mL
So,
The expression for the calculation of density is shown below as:-
Using the above expression to calculate the mass as:-
Applying the values to calculate the mass as:-
<u>The mass of titanium displaces 68.6 mL of water is 309.4 g.</u>
