1. No, it doesn't.
2. 4 Hydrogen atoms are on the reactants side and 2 hydrogen atoms on products side.
3. Because the mass of reactants is not equal to the mass of the products thus it doesn't follow the law of conservation of matter.
But on balancing the eqn,
CH4 + 2O2 > CO2 + 2H2O
The above eqn will follow the law of conservation of matter because the mass of reactants is equal to the mass of products.

How did james Chadwick know that neutrons are neutral ?
Answer:
In 1932, he tried similar experiments himself, and became convinced that the radiation ejected by the beryllium was in fact a neutral particle about the mass of a proton. ... Chadwick also noted that because the neutrons had no charge, they penetrated much further into a target than protons would.

Answer:
Streak
Explanation:
Streak is the microscopic remains of minerals in powder form after being rubbed with porcelain plates. The streaks do not have orderly arranged lattice structure or unit cells.
They are randomly arranged and microscopic size powders. The streak of minerals cannot be distinguished easily as it mostly appears similar for all minerals.
Thus, among the given options streak is one in the property of minerals. We can rely upon streaks as it cannot be easily affected by impurities.

Explanation:
Solids have a definite shape and volume. Liquids have a definite volume, but take the shape of the container. Gases have no definite shape or volume.
The kinetic theory of matter (particle theory) says that all matter consists of many, very small particles which are constantly moving or in a continual state of motion.

How many moles of HCl will be produced when 34.56 g of AIC3 are reacted according to this chemical equation
Answer:The answer to your question is It will be formed 0.39 moles of H₂
Data
moles of H₂ = ?
moles of HCl = 0.78
moles of Zinc = excess
Balanced chemical reaction
2 HCl + Zn ⇒ 1 H₂ + ZnCl₂
Process
Explanation:
1.- Use proportions to solve this problem. Consider the coefficients of the balanced reaction.
2 moles of HCl ---------------------- 1 mol of H₂
0.78 moles of HCl ----------------- x
x = (0.78 x 1) / 2
- Simplification
x = 0.78 / 2
- Result
x = 0.39 moles of H₂

How do the metals in group 1 compare with the transition metals?
Answer:
Group 1 metals and transition metals are different from each other, mainly based on the colour of the chemical compounds that they form. The key difference between group 1 metals and transition metals is that the group 1 metals form colourless compounds, whereas the transition metals form colourful compounds.
What is empirical evidence
A retest of experimental results to make them reliable
Knowledge gained by observation or measurement
A prediction of test results before an experiment
A conclusion derived from evidence and logical reasoning
According to the kinetic molecular theory, the pressure of a gas increases as
the number of moles of gas molecules increases because —
Answer:
The volume of the gas therefore becomes large as the temperature of the gas increases, the frequency of collisions with the walls of the container must increase. This, in turn, leads to an increase in the pressure of the gas.

Write the law of conservation of matter…
(Please Answer fast)
Answer:
The Law of Conservation of Matter states that matter cannot be created or destroyed. In a physical change, substances can change form, but the total mass remains the same. In a chemical change, the total mass of the reactants always equals the total mass of the products. Materials.

what kind of chemical processes are used to create these synthetic products
Aluminium is a natural material that is widely utilised in a variety of sectors and may be converted into a variety of synthetic goods via various chemical processes.
The following are some examples of synthetic compounds created from aluminium and the accompanying chemical processes:
Aluminium Foil: Aluminium foil is a thin, flexible sheet of metal.Aluminium Cans: Aluminium cans used for beverage packaging are created through a process known as can forming. Aluminium alloys are synthetic goods formed by mixing aluminium with additional elements such as copper, zinc, magnesium, or silicon.Thus, these are only a few examples of synthetic goods generated from aluminium and the chemical processes that produce them.
