CO2 +
H2O
Answers
Answer: [tex]C_3H_8+5O_2\rightarrow 3CO_2+4H_2O[/tex]
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The balanced chemical equation for combustion of propane will be :

why is it important that the level of the sea water does not go above the level of the filter paper
Answers
Answer:
The water (the substance) that passes through the filter paper is called the filtrate. If your mixture is a solution, such as salty water, then filtering will not separate the salt from the water. Instead, by heating the soluton the solvent (water) evaporates leaving the solid (salt) behind.

Describe two differences between transition elements and alkali metals?
Answers
Explanation:
On the periodic table, we can find a wide range of elements from alkali metals, to the alkali earth metals, transition metals and through to the noble gases.
The alkali metals are found on the first group in the periodic table and they are group of metals. Also, the transition elements are also a group of metals.
Transition elements are known to have variable oxidation states whereas, alkali metals have an oxidation state of +1. Transition metals belong the d-block on the periodic table whereas alkali metals are found in the first group on the periodic table.Balance the following equations:C(s) +CO2(g)- CO(g)

It has been an expense for the Australian government (taxpayers) to try to control the rabbit population
Question 4 options:
True
False
Answers
Answer:
true
Explanation:
It has been an expense for the Australian government (taxpayers) to try to control the rabbit population. This statement is true.
Why did the rabbit population grow so quickly in Australia?Aside from the lack of natural predators on the continent, their success is aided by rapid reproduction: They can have more than four litters a year, each with up to five kits (baby rabbits).
The European wild rabbit has become an invasive pest in the southern two-thirds of Australia. They have an impact on natural environments, primary production, as well as townships and infrastructure.
The government turned to biocontrol in the 1950s. They released rabbits infected with myxoma, a virus that only affects rabbits, into southeastern Australia.
Thus, It has been an expense for the Australian government (taxpayers) to try to control the rabbit population. This statement is true.

Consider the following reaction, which occurs at standard state:
2CI(g) -- CI2(g) H= -243.4 kJ
If 15.0g of CI is concerted to chlorine, determine the heat released from this reaction.
Answers
Answer:
The heat energy released from the reaction is approximately 51.4791 kJ
Explanation:
The given parameters are;
The heat of the reaction of 2Cl (g) → Cl₂ (g) = -243.4 J
The given mass of Cl being converted to chlorine gas, Cl₂ = 15.0 g
From the reaction for the heat of formation, we have;
2 moles of chlorine produces 1 mole of Cl₂ to release 243.4 kJ of energy per mole of Cl₂
The mass of 1 mole of Cl ≈ 35.453 g
Therefore, from number of moles, n = Mass/(Molar Mass), we have;
The number of moles of chlorine, in 15.0 g of chlorine = 15.0/35.453 ≈ 0.423 moles
Therefore, given that 2 moles of Cl produces 1 mole of Cl₂, we have;
0.423 moles of Cl will produce 0.423/2 ≈ 0.2115 moles of Cl₂
The heat energy released from the reaction is therefore, H ≈ 0.2115 × 243.4 kJ = 51.4791 kJ.

Answers
The forming of bubbles when baking soda and vinegar are mixed is a result of chemical property.
Chemical PropertiesChemical properties of materials are properties that are due to the chemical composition of the materials.
The formation of bubbles when baking soda is mixed with vinegar is a result of the evolution of carbon dioxide gas.
Baking soda reacts with vinegar to produce carbon dioxide and other products according to the chemical equation below:
NaHCO3 + CH3COOH → CO2 + H2O + CH3COONa

Answers
Answer:
C) Potassium, K, and calcium, Ca
Explanation:
Given pair of elements:
Ni and Cu
Potassium and Ca
Nitrogen and oxygen
Solution:
We know that number of protons and number of electrons are always equal and number of electron or number of proton is called atomic number.
Number of protons given elements:
Ni number of protons = 28
Copper number of protons = 29
Combine number of protons = 57
K number of protons = 19
Ca number of protons = 20
Combine number of protons = 39
Ni number of protons = 7
O number of protons = 8
Combine number of protons = 15
Thus, option C is correct.
why are cells small?
Answers
Answer:
you know what i really dont know but imagine if they were huge
Explanation:
They are also small so they can maximize the ratio of surface area to volume. Smaller cells have a higher ratio which allows more molecules and ions move across the cell membrane per unit of cytoplasmic volume.
basically cells are small because they need to be able to get the nutrients in and waste out quickly.
