Answer: Increase in the greenhouse effect

Explanation: Green house effect is a phenomenon which takes place in the earths lower atmosphere making it a place to live.

In this process, the infrared radiations emitted by the sun are being trapped by some of the gases which are known as Greenhouse Gases.

These rays emitted from the sun are very harmful and they could cause hazardous diseases if reached to the earths atmosphere.

Greenhouse Gases are Nitrous Oxide, Carbon dioxide, Methane , water vapor and ozone.

Thus if the concentration of any of the gases will increase in the atmosphere, it will lead to the increase in the greenhouse effect.

Consider the equation: S+302 →SO3 Is this equation balanced? Why or why not?

Talja [164]

No, because there’s 6 Oxygens going in and only 3 going out. To balance:
2S+3O2 -> 2SO3

Part APart complete A sample of sodium reacts completely with 0.568 kg of chlorine, forming 936 g of sodium chloride. What mass

yan [13]

Answer: 368 grams of sodium reacted.

Explanation:

The balanced reaction is :

$2Na(s)+Cl_2(g)\rightarrow 2NaCl(s)$

$\text{Moles of chlorine}=\frac{\text{given mass}}{\text{Molar Mass}}$

$\text{Moles of chlorine}=\frac{0.568\times 1000g}{71g/mol}=8moles$

$\text{Moles of sodium chloride}=\frac{936g}{58.5g/mol}=16mol$

According to stoichiometry :

2 moles of $NaCl$ are formed from = 2 moles of $Na$

Thus 16 moles of $NaCl$ are formed from= $\frac{2}{2}\times 16=16moles$ of $Na$

Mass of $Na=moles\times {\text {Molar mass}}=16moles\times 23g/mol=368g$

Thus 368 grams of sodium reacted.

Write electron configurations for Gallium, Ga (Z=31), and show the total valence electrons

ivann1987 [24]

Answer: The electronic configuration of gallium is written below and number of valence electrons is 3.

Explanation:

Electronic configuration is defined as the representation of electrons around the nucleus of an atom.

Number of electrons in an atom is determined by the atomic number of that atom.

Valence electrons are defined as the electrons present in the outermost shell of an atom.

We are given:

An element Gallium having atomic number as 31.

Number of electrons = 31

Electronic configuration of Gallium is: $(Z=31):1s^22s^22p^63s^23p^64s^23d^{10}4p^1$

This element has 3 electrons in its outermost shell. So, the number of valence electrons is 3

Hence, the electronic configuration of gallium is written below and number of valence electrons is 3.
