Answer:

Cation = Mn³⁺

Anion = CO₃²⁻

Explanation:

An ionic compound is formed by a combination of positive and negative ions that are held together by ionic bonds.

The positively charged ions have a tendency to lose electrons and are called cations. In contrast the negatively charged ions called anions show a tendency to accept or attract electrons. In general, metals show a propensity to lose electrons thereby forming cations.

The given compound is: Mn₂(CO₃)₃ i.e. manganese carbonate

Here, manganese Mn is a transition metal and therefore will be the cation.

The anion is the polyatomic species, carbonate which carries a charge of -2.

Since the molecule is neutral the charges need to be balanced. If the charge on Mn is say'x' then:

2x +(3)(-2) = 0

i.e. x = +3

Hence:

Cation = Mn³⁺

Anion = CO₃²⁻

5.60 g of an unknown gas at STP fills a 500 mL flask. What is the molar mass of the gas

ale4655 [162]

Hey there!

From ideal gas equation we know, PV = nRT

All the terms have their usual significance.

PV =w/M * RT

( where , n is number of moles = w/M, we = weight of gas, M = molecular weight of the gas)

Therefore, PV = wRT/M

At standard conditions , value of pressure, P = 1atm and standard temperature, T = 273K

And value of universal gas constant, R = 0.082 lit. atm. K⁻¹.mol⁻¹

Given that, weight of gas,

w = 5.60g and volume of gas,

V = 500mL = 0.5 Liters

Therefore, substituting all the value, we get :

Molar mass = 5.60 * 0.082 * 273 / 1 * 0.5

Molar mass = 250.7232 g/mole

At the end of seafloor spreading, where does the molten rock solidify?

olganol [36]

Answer:

As the two plates move apart from each other, which often occurs at a rate of several centimetres per year, molten rock wells up from the underlying mantle into the gap between the diverging plates and solidifies into new oceanic crust. Spreading centres are found at the crests of oceanic ridges.

Cecilia and tegan are learning about things that dissolve in water. They put sugar into a cup of water and saw that the sugar be

damaskus [11]

Answer:

1. stir with a spoon

Explanation:

if you stir the water with a spoon, it quickens the process at which the sugar dissolves. The spoon you could say also speeds it all up. Think of it this way, a meteor entering earths atmosphere, will it get smaller faster going 50 mph, or 100mph? the regular is 50, but when you got the spoon, it increases (more gravity force on the meteor= that 100mph).

hope this helps.

Find energy is the wavelength is 5.2x10^-7m (Show work)

RoseWind [281]

Answer:

E = 3.825×10⁻¹⁹ J

Explanation:

Wavelength of photon = 5.2 ×10⁻⁷m

Energy of photon = ?

Solution:

Formula:

E = hc/λ

h = plancks constant = 6.63×10⁻³⁴ Js

c = speed of wave = 3×10⁸ m/s

by putting values,

E = 6.63×10⁻³⁴ Js ×3×10⁸ m/s / 5.2 ×10⁻⁷m

E = 19.89×10⁻²⁶ J.m / 5.2 ×10⁻⁷m

E = 3.825×10⁻¹⁹ J
