The value of density in kg/m³ is equal to 0.00088 kg/m³.
What is the metric system?The metric system can be demonstrated as a system of measurement that is composed after the decimalized system based on the meter. Each of the fundamental dimensions can be represented by a single base unit of measurement.
For parameters derived from the base units of the system, units derived from the base units can be used such as the square meter being the derived unit for the area, a parameter derived from length.
Metric units can be defined as units based on the gram, meter, or second and decimal multiples.
Given the density in the unit of g/cm³.
Density = 0.0088 g/cm³
We know that 1 Kg = 1000 g
⇒ 1 g = 10⁻³ Kg
We know that 1 m = 100cm
1 cm = 10⁻² m
Therefore, Density = 0.0088 × 10⁻³Kg/10⁻² m³
Density = 0.00088 kg/m³

1. What pressure would be exerted by 46.0grams of hydrogen gas placed into a 3.00 L container at
25°C?
Answer:
187.34 atm
Explanation:
From the question,
PV = nRT.................. Equation 1
Where P = Pressure, V = Volume, n = number of mole, R = molar gas constant, T = Temperature.
make P the subject of the equation
P = nRT/V.............. Equation 2
n = mass(m)/molar mass(m')
n = m/m'............... Equation 3
Substitute equation 3 into equation 2
P = (m/m')RT/V............ Equation 4
Given: m = 46 g, T = 25°C = (25+273) = 298 K, V = 3.00 L
Constant: m' = 2 g/mol, R = 0.082 atmL/K.mol
Substitute these values into equation 4
P = (46/2)(0.082×298)/3
P = (23×0.082×298)/3
P = 187.34 atm

In the reaction above, how many moles of sodium chloride would be produced
if you started with 20 grams of magnesium chloride and excess sodium
phosphate? The equation is not balanced.
(If anyone can answer in depth if appreciate it )
Answer:
24.5 g of NaCl
Explanation:
We begin from the balanced reaction:
3MgCl₂ + 2Na₃PO₄ → 6NaCl + Mg₃(PO₄)₂
If the sodium phosphate is in excess, then the limting reagent is the magnessium chloride.
We convert mass to moles:
20 g . 1mol / 95.2g = 0.210 moles.
3 moles of MgCl₂ can produce 6 moles of NaCl
0.210 moles of salt, may produce (0.210 . 6) /3 = 0.420 moles
Ratio of reactant is twice the product
We convert the moles to mass:
0.420 mol . 58.45 g/mol = 24.5 g

A reaction is first order with respect to reactant A and second order with respect to reactant B. Starting with [A] = 0.175 M and [B] = 0.00250 M, the reaction rate is 2.83 x 10−5 M.S−1. What is the rate constant k? Show your work.
Answer:
[tex]k=25.9M^{-2}s^{-1}[/tex]
Explanation:
Hello there!
In this case, since rate laws are written by considering the rate constant, concentration and specific orders of reaction of the concentration of the species contributing to the rate of reaction, we write:
[tex]r=k[A][B]^2[/tex]
Since it is first-order with respect to reactant A and second-order with respect to reactant B. In such a way, given the rate and concentrations of both A and B, the involved rate constant k turns out to be:
[tex]k=\frac{r}{[A][B]^2} \\\\k=\frac{2.83x10^{-5}M/s}{(0.175M)(0.00250M)^2}\\\\k=25.9M^{-2}s^{-1}[/tex]
Best regards!

What happens with electrons in a non-polar bond?
Brainliest!!!!!!!
Answer:
In a nonpolar covalent bond, the atoms share electrons equally with one another.
Explanation:
Nonpolar covalent bonds are a type of bond that occurs when two atoms share a pair of electrons with each other. These shared electrons glue two or more atoms together to form a molecule.

How can the properties of acids and bases be used to classify solutions?
Answer:
Acids and bases aqueous solutions will conduct electricity because they contain dissolved ions. Therefore acids and bases are electrolytes. strong acids and bases will be electrolytes. weak acids and bases will be weak electrolytes.
What is the average speed of a race car if it travelled a total of 500 miles in 3.5 hours
Answer:
speed = 142.8571 miles per hour OR 142.8571 mi/h
Explanation:
speed= [tex]\frac{distance}{time}[/tex]
distance = 500, time = 3.5hours or 210 minutes
speed= [tex]\frac{500}{210}[/tex] = 142.8571

A 12.8-g sample of sodium completely reacts with 19.6 g of chlorine to form 32.4 g of sodium chloride. These data are A 12.8-g sample of sodium completely reacts with 19.6 g of chlorine to form 32.4 g of sodium chloride. These data are blank with the law of conservation of mass because the mass of reactants blank the mass of products. with the law of conservation of mass because the mass of reactants A 12.8-g sample of sodium completely reacts with 19.6 g of chlorine to form 32.4 g of sodium chloride. These data are blank with the law of conservation of mass because the mass of reactants blank the mass of products. the mass of products.
Answer: The data are consistent with the law of conservation of mass because the mass of reactants equals the mass of products
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.
Given: mass of sodium = 12.8 g
mass of chlorine = 19.6 g
mass of reactants = mass of sodium + mass of chlorine = 12.8 g + 19.6 g = 32.4 g
Mass of product = Mass of sodium chloride = 32.4 g
As mass of reactant = mass of products , Thus results are in accordance with the law of conservation of mass.

If 27.3g of C8H18 is combusted, according to the equation below, what mass of water is produced?
2C8H18 + 25O2 --> 16CO2 + 18 H2O,
molar masses: C8H18 = 114.3 g/mol O2 = 32.0 g/mol CO2 = 44.0 g/mol H2O = 18.0 g/mol
Answer:
38.7 g
Explanation:
2C₈H₁₈ + 25O₂ → 16CO₂ + 18 H₂OFirst we convert 27.3 grams of C₈H₁₈ into moles, using the given molar mass:
27.3 g C₈H₁₈ ÷ 114.3 g/mol = 0.239 mol C₈H₁₈Then we convert 0.239 moles of C₈H₁₈ into moles of H₂O, using the stoichiometric coefficients of the reaction:
0.239 mol C₈H₁₈ * [tex]\frac{18molH_2O}{2molC_8H_{18}}[/tex] = 2.151 mol H₂OFinally we convert 2.151 moles of H₂O into grams, using water's molar mass:
2.151 mol H₂O * 18.0 g/mol = 38.7 gHow many molecules of water are there in 10 lbs of water?

Why does the moon have a stronger gravitational effect on the earth then the sun?
Explanation:
The tidal forces of the Moon are much stronger than the Sun's because it is so much closer to our planet, causing a much greater variation in the gravitational force from one location to another. The Sun's gravitational force, on the other hand, varies much less because the Sun is so far.
