How do tectonic plates move at convergent subduction boundaries? Insert a drawing with the arrows that show the movement
Answer:
If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. ... As the sinking plate moves deeper into the mantle, fluids are released from the rock causing the overlying mantle to partially melt.

find the molar mass of this
Explanation:
Given problem:
Find the molar mass of:
SO₃ and C₁₀H₈
Solution:
The molar mass of a compound is the mass in grams of one mole of the substance.
To solve this, we are going to add the individual atomic masses of the elements in the compound;
Atomic mass;
S = 32g/mol; O = 16g/mol; C = 12g/mol and H = 1g/mol
For SO₃;
= 32 + 3(16)
= 32 + 48
= 80g/mol
For C₁₀H₈
= 10(12) + 8(1)
= 120 + 8
= 128g/mol

Answer:
nonmetel
Explanation:
Answer:
Its a non-metal
Explanation:
Elements that tend to gain electrons to form anions during chemical reactions are called non-metals. These are electronegative elements. They are non-lustrous, brittle and poor conductors of heat and electricity (except graphite). Non-metals can be gaseous, liquids or solids.

Explain how Newton’s third law of motion applies to a system of objects
Answer:
Newton's third law of motion states that whenever a first object exerts a force on a second object, the first object experiences a force equal in magnitude but opposite in direction to the force that it exerts. Newton's third law is useful for figuring out which forces are external to a system

How are oxidation states of transition metals indicated in the names of metal
compounds?
A. Prefixes are used to indicate oxidation states.
B. Group numbers are used to indicate oxidation states.
C. Roman numerals are used to indicate oxidation states.
D. Subscripts are used to indicate oxidation states.
Answer:
The anser is c
Roman numerals are used to indicate oxidation states. Hence, option C is correct.
What is the oxidation state?An oxidation state is a number given to the atom of an element when participating in a chemical reaction.
Roman numerals are used to indicate oxidation states of transition metals.
The names for transition metal compounds often have roman numerals in them, because the roman numerals indicate the charge on the transition metal. But the oxidation state of Cu in CuO is +2, and the oxidation state of Cu in [tex]Cu_2O[/tex] is +1. Name metal first and charge and transition metal with a roman numeral.
The transition metals may form more than one ion, thus it is needed to be specified which particular ion we are talking about. This is indicated by assigning a Roman numeral after the metal. The Roman numeral denotes the charge and the oxidation state of the transition metal ion.
[tex]Fe^{2+}[/tex] would be named iron (II) and [tex]Fe^{3+}[/tex] would be named iron (III).
Hence, option C is correct.

If 0.484J of heat is added to 0.1372g of water, how much will the temperature increase?
0.263 °C
0.927 °c
0.843 °C
0.460 °C
Answer:
ΔT = 0.843 °C
Explanation:
Given data:
Heat added = 0.484 J
Mass of water = 0.1372 g
Temperature increase = ΔT = ?
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Specific heat capacity of water is 4.184 j/g.°C
Now we will put the values in formula.
0.484 j = 0.1372 g × 4.184 j/g.°C× ΔT
0.484 j = 0.574j/°C× ΔT
ΔT = 0.484 j / 0.574j/°C
ΔT = 0.843 °C

what is the density of aluminum if you have a piece of aluminum that is 10.5cm x 10.5cm x 0.1cm and has a mass of 29.8 grams?
Answer:
2.7g/cm³
Explanation:
Given parameters:
Dimension of the aluminum = 10.5cm x 10.5cm x 0.1cm
Mass of the aluminum = 29.8g
Unknown:
Density = ?
Solution:
Density of a substance is its mass per unit volume;
Mathematically;
Density = [tex]\frac{mass}{volume}[/tex]
Volume of the aluminum = 10.5cm x 10.5cm x 0.1cm = 11.025cm³
So, insert the parameters and solve;
Density = [tex]\frac{29.8}{11.025}[/tex] = 2.7g/cm³
