Which is the correctly balanced chemical equation for the reaction of KOH and H2SO4? Upper K upper O upper H right arrow upper H
sertanlavr [38]

Answer :

The balanced chemical reaction will be,

H_2SO_4+2KOH\rightarrow K_2SO_4+2H_2O

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.

The coefficient tell us about that how many molecules or atoms present in the chemical equation.

When sulfuric acid react with potassium hydroxide then it react to give potassium sulfate and water as a product. This reaction is known as acid-base reaction.

The balanced chemical reaction will be,

H_2SO_4+2KOH\rightarrow K_2SO_4+2H_2O

A block of wood has a volume of 64 cm3 and a mass of 46 grams. What is the density of the block?
Rom4ik [11]

The correct answer is 0.72 g/cm3

Explanation:

The density of a material depends on both its mass (amount of matter), which is usually provided in grams (g), and its volume (space occupied), which is provided in units such as cubic centimeters cm3. Moreover, to find how dense the material is, take the mass and divide it into the volume. The process for finding the density of the block of wood is shown below:

d = \frac{m}{v}

d = \frac{46 g}{64 cm3}

d = 0.718 g/cm3

This means the density is 0.71g/cm3 and this can be rounded to 0.72 g/cm3

List 10 uses of composite​
REY [17]

Aerospace

Thermoset composites are being specified for wings, fuselages, bulkheads, and other applications in commercial, civilian and military aerospace applications.

Appliance/Business

Thermoset composite are being used in frames, equipment panels, handles and trims in appliances, power tools, business equipment and many other applications.

Thermoset composites for the appliance industry are used in washers, dryers, refrigerators, freezers, ranges, ovens, dishwashers for components that include control panels, handles, knobs, vent trims, side trims, motor housings, kick plates and many others.

Automotive/Transportation/Farm/Construction

Composites are now being used in vehicle and equipment applications, including, panels, frames, interior components and other parts.

Civil Infrastructure

Some composite infrastructure applications include buildings, roads, bridges and pilings.

Construction

Thermoset composites are replacing many traditional materials for home and offices architectural components including fixtures, doors, wall panels, roofing, window frames, moulding, vanity sinks, shower stalls and even swimming pools.

Corrosive Environments

Composites are ideal for applications in corrosive environments, such as chemical processing plants, pulp and paper converting, oil and gas refineries and water treatment facilities.  Common applications include fans, grating, tanks, ducts, hoods, pumps and cabinets.

Electrical

With strong dielectric properties including arc and track resistance, Thermoset components include substation equipment, microwave antennas, standoffs and pole line hardware and printed wiring boards. Applications and components include switchgear,  motor controls,  standoff insulators, control system components,  circuit breakers,  arc chutes, arc shields, terminal blocks,  terminal boards,  metering devices,  bus supports and lighting components.

Marine

With their corrosion resistance and light-weighting attributes, Marine composite applications include boat hulls, bulkheads and other components for military, commercial and recreational boats and ships.

5. What is the mass of 9.80 x 1023 formula units of zinc chlorate, Zn(CO3)2?
Zielflug [23.3K]

Answer:

\boxed{\text{378 g}}

Explanation:

We must convert formula units of Zn(ClO₃)₂ to moles and then to grams of Zn(ClO₃)₂.

Step 1. Convert formula units to moles

\text{Moles of Zn(ClO$_{3}$)$_{2}$}\\\\= 9.80 \times10^{23}\text{ formula units Zn(ClO$_{3}$)$_{2}$} \times \dfrac{\text{1 mol Zn(ClO$_{3}$)$_{2}$}}{6.022 \times\ 10^{23} \text{ formula units Zn(ClO$_{3}$)$_{2}$}}\\\\= \text{1.627 mol Zn(ClO$_{3}$)$_{2}$}

Step 2. Convert moles to grams

\text{Mass of Zn(ClO$_{3}$)$_{2}$}\\\\= \text{1.627 mol Zn(ClO$_{3}$)$_{2}$} \times \dfrac{\text{232.29 g Zn(ClO$_{3}$)$_{2}$}}{\text{1 mol Zn(ClO$_{3}$)$_{2}$}}\\\\= \text{378 g Zn(ClO$_{3}$)$_{2}$}\\\\\text{The mass of Zn(ClO$_{3}$)$_{2}$ is } \boxed{\textbf{378 g}}
