Answer:
Explanation:
The question wants us to determine what could be done to change the carbide ion to a neutral carbon atom.
From the given information:
The dark grey ball has a +1 charge, which implies that the positive charge is the proton. Also, the light grey ball is denoted by 0 charge, which signifies that it is a neutron because a neutron usually has no charge, and its mass is equal to the mass of the proton.
Consequently, the -1 charge on the medium grey ball signifies that it is an electron.
In a neutral atom, the number of protons usually equal to the electron number. However, in as much as no overall charge is present from the model of the atom given. We can say that the atom is neutral.
Let also recall that the atomic number is the number of available protons present in the element's atomic nucleus.
Thus, in the given atom.
The total number of proton = 8
The total number of neutron = 9
The total number of electron = 8
Since atomic number relates to the number of protons, the atomic number is also = 8
Answer: C :)
remove 4 electrons

Explanation:
When heat is produced by a reaction, would you call it a chemical change?
Answer:
However, in this case, one compound is mixed in with another, and these reactants produce a product. When the reactants are mixed, the temperature change caused by the reaction is an indicator of a chemical change. This reaction generates heat as a product and is (very) exothermic.

Imagine that you heat a pot of water to a boil (212°F), then you turn off the stove and let the water sit there. The room is at room temperature (72°F) What temperature do you predict the water cool to after sitting for 8 hours? (
Answer:
72 °F
Explanation:
Hello,
In this case, since matter tend the be stable at conditions they do not change, if we have water at room temperature (72 °F) and we heat it until boiling but then we turn off the stove, we molecularly see that due to the heat, the molecules start moving faster and crashing to each other; however when that fed energy starts being removed as the stove gets turned off, the molecules lose energy causing them to start moving slower so they lose energy until a point the remain at the initial status, that is 72 °F because thermal equilibrium is reached. Therefore it is likely for the water to be at 72 °F as well once 8 hours have passed, because a thermal equilibrium is reached with the environmetnal temperature.
Best regards.

A tide with the largest difference between water levels at high and low tides is known as a spring tide. Two spring tides occur in each lunar cycle. This is because a spring tide occurs when the Moon
A
is closest to Earth.
B
and the Sun pull on Earth at a 90° angles.
C
and the Sun are aligned and pull on Earth.
D
is farthest from Earth.
Answer:
C is the answer
Explanation:
Tidal cycles are affected by lunar day, semidiurnal and diurnal, lunar nodes, axial tilt ... Their tidal forces act to reinforce each other, and the ocean both rises higher and ... Tidal ranges - differences between neap tides and spring tides - graph ... The perigee of the moon can occur at any point in the orbit around the earth due ...
The correct option is option C among all the given options. This is because a spring tide occurs when the Moon and the Sun are aligned and pull on Earth.
What is tide?Any periodic deformation of one astronomical entity brought on by the gravitational pull of another is referred to as a tide. The most well-known are the regular fluctuations in Earth's sea level that are caused by shifts in the Sun's and Moon's relative locations. You can think of the tides as driven waves, flowing waves, and standing waves.
A tide with the largest difference between water levels at high and low tides is known as a spring tide. Two spring tides occur in each lunar cycle. This is because a spring tide occurs when the Moon and the Sun are aligned and pull on Earth. The Moon's ability to produce tides results from changes inside its gravitational field across Earth's surface in comparison to its strength at the planet's center.
Therefore, the correct option is option C among all the given options.

True or False: Mechanical weathering is the breakdown or rock by changing its chemical composition.
Answer: False
Explanation:
That’s not using mechanics
Answer:
False
Explanation:
Mechanical weathering breaks rocks into smaller pieces without changing their composition. Ice wedging and abrasion are two important processes of mechanical weathering. Chemical weathering breaks down rocks by forming new minerals that are stable at the Earth's surface.

When an unknown amount of methane reacts with 40.7 g of chlorine, 40.5 g of methyl chloride and 36.5 g of hydrogen chloride form how much methane was used round to the tenth
Answer:
36.3 gram
Explanation:
CH₄ + Cl₂ = CH₃Cl + HCl
In any reaction , mass is conserved
mass of product = 40.5 + 36.5 = 77 g
Let methane reacted be x .
mass of reactant = x + 40.7
mass of reactant = mass of product
x + 40.7 = 77
x = 36.3 gram
methane reacted = 36.3 gram.

what is 23.54 kg x 9.8 m/s2
Answer:
230.692
Explanation:
23.54kg*9.8m/s²= 230.692
Answer:
F = 230.69 N
Explanation:
Given data:
Mass = 23.54 Kg
Acceleration = 9.8 m/s²
Force = ?
Solution:
Mass ×Acceleration is equal to force.
F = 23.54 Kg × 9.8 m/s²
F = 230.69 Kg.m/s²
Kg.m/s² = N
F = 230.69 N
