When magnesium metal is burnt in air it reacts with both oxygen and nitrogen gses giving a white ash write to equatios for the reactions that take place
Answer:
See explanation
Explanation:
The most important thing to bear in mind when writing chemical reaction equation is that the equation must be balanced. A balanced chemical reaction equation is one in which the number of atoms of each element on the left and right hand sides of the reaction equation is exactly the same.
Equation of magnesium reaction with oxygen
2Mg(s) + O2(g) ------> 2MgO(s)
Equation of magnesium reaction with nitrogen
3Mg(s) + N2(g) ------> Mg3N2(s)

What is the specific heat of silicon if the temperature of a 4.11 g sample of silicon
is increased by 3.8 °C when 11.1 J of heat is added?
Answer:
The right solution is "0.7107 J/g°C".
Explanation:
The given values are:
Mass,
m = 4.11 g
Temperature,
ΔT = 3.8°C
Heat,
Q = 11.1 J
The specific heat of silicon will be:
⇒ [tex]C=\frac{Q}{m \Delta T}[/tex]
On substituting the values, we get
⇒ [tex]=\frac{11.1}{4.11\times 3.8}[/tex]
⇒ [tex]=\frac{11.1}{15.618}[/tex]
⇒ [tex]=0.7107 \ J/g^{\circ}C[/tex]

LA of certain mass occupies a volume of 650 cm3 under
a pressure of 760mmHg. Calculate the pressure under which
the volume of the
gas
cent
of its original volume
will be reduced by 10 per
Answer:
844.4cm³
Explanation:
Using Boyle's law equation;
P1V1 = P2V2
Where;
P1 = initial pressure (mmHg)
P2 = final pressure (mmHg)
V1 = initial volume (cm³)
V2 = final volume (cm³)
According to the information in this question,
V1 = 650cm³
P1 = 760mmHg
P2 = ?
V2 = 10% reduction of V1
10% of 650 = 10/100 × 650
65
V2 = 650 - 65 = 585cm³
Using P1V1 = P2V2
P2 = P1V1 ÷ V2
P2 = (760 × 650) ÷ 585
P2 = 494000 ÷ 585
P2 = 844.44
final pressure (P2) = 844.4cm³
Is a shrimp an arachnid?
is a pill bug a insects, arachnid, or crustaceans?
is a scorpions a insects, arachnid, or crustaceans?
Answer:
Insects belong to the class Insecta, and arachnids to the class Arachnida; both classes fall under the Arthropoda phylum, along with crustaceans (crabs, lobster and shrimp). All arthropods have an exoskeleton and jointed legs. They have segmented bodies and appendages, which are divided into different segments. Arachnids belong to an even larger group of animals called “arthropods” which also include insects and crustaceans (lobster, crabs, shrimp, and barnacles).

2. What coefficients would balance the following equation?
_C2H6 +_027_C02 +_H20
A. 1C2H6 + 502 – 2002 + 3H20
B. 2C2H6 + 502 + 4002 + 6H20
O C. 2C2H6 + 702 4CO2 + 6H20
O D. 2C2H6 + 1002 > 4CO2 + 6H20
Answer:
C
Explanation:
Assuming you had a few typos in the equations, I would say C
I am going to assume the reaction
_C2H6 + _O2 → _CO2 + _H2O
Right now, there is enough hydrogen to make 3 water molecules, but since oxygen comes in groups of 2, it wouldn't work.
Therefore, we need 2 ethane molecules.
2C2H6 + _O2 → _CO2 + _H2O
Then balance the right side with the carbons and hydrogens
2C2H6 + _O2 → 4CO2 + 6H2O
So we need 4 O2's in carbon dioxide and 3 O2's in water (Since water uses 1 oxygen molecule per 2 hydrogens). Hence we will need 7 oxygens
2C2H6 + 7O2 → 4CO2 + 6H2O
And assuming errors in the typing, C should be the answer (if this matches)

Answer:
5. Amplitude.
6. 344.8 meters/second
Explanation:
5. The energy is proportional to the amplitude is all I remember. Sorry :/ Been a long time since I took these classes.
6. Traveling to the wall & back is 200m
100 + 100 = 200m total traveled
The time is 0.58s so, we can use the speed formula to solve [ s = d/t ] where s = speed, d = distance, and t = time.
s = 200/0.58
s = 344.82758
I don’t know if they’ll have you round, but I would say the speed of the sound is 344.8 m/s.

Before reaction : 4 Cu2+ molecules and 8NO3-
Answer:
There is too much here for me to attempt in one sitting, but I will get you started and give suggestions that may help you proceed on your own.
a) As far as I can tell, you didn't provide the reduction potentials in the table below. So, I looked them up and find them to be
Cu2+ +2e- ==> Cu(s) Eº = +0.34 V
Zn2+ + 2e- ==> Zn(s) Eº = -0.76 V
Net ionic equation: Cu2+(aq) + Zn(s) ==> Cu(s) + Zn2+(aq)
b) Eºcell = 0.34 V + 0.76 V = 1.10 V
c) ∆Gº = -nFEº where n = number of electrons transferred (2) and F = 96,485 C/mol e- and Eº = 1.1 V
d) Again, there is no diagram
e) same
f) Use the Nernst equation Ecell = Eºcell - 2.303RT/nF log Q where R = 8.314; T = Kelvin; F = Faraday const. and Q = reaction quotient, i.e. products/reactants
g) the cell voltage is an intensive property. That should help you answer this part of the question

its not much but i hoped this helped
