2,3,6,1

Explanation:

The unbalanced reaction expression is given as:

  AlBr₃    +    K₂SO₄  →    KBr  + Al₂(SO₄)₃

We need to balanced this reaction equation. Our approach is a mathematical method where we assign variable a,b,c and d as the coefficients.

 aAlBr₃    +    bK₂SO₄  →    cKBr  + dAl₂(SO₄)₃

Conserving Al;  a  = 2d

                   Br:  3a  = c

                   K:   2b = c

                   S:   b  = 3d

                   O:  4b  = 12d

Let a  = 1, c = 3, d  = [tex]\frac{1}{2}[/tex]  b  = [tex]\frac{3}{2}[/tex]  

 Multiply through by 2 to give;

     a  = 2, b = 3, c = 6 and d  = 1

 2AlBr₃    +    3K₂SO₄  →    6KBr  + Al₂(SO₄)₃

jowl is a derived unit give reason​

Answers

Answer:

Explanation:

Joule is the unit of energy and work done.

It is a derived quantity because it is not a fundamental or basic unit.

A derived unit is formed by the combination of two or more fundamental quantities.

Since work done  = Force x distance

                           Force  = mass x acceleration

                          = mass x acceleration x distance

The unit then becomes kgm²/s²

So, 1joule  = 1kgm²/s²

Question: How many grains of rice are in a 453.6 g (1lb.) bag of rice?



The rice is white.

The height of the bag of rice is 2.54 cm.

The length of the bag of rice is 20 cm.

The width of the bag of rice is 8 cm.

A grain of rice has a length of 6.0 mm.

20 grains of rice weigh .58 grams.

Answers

Answer:

453.6/58/2=453.6/2.9=156.314 grains

The number of grains in a 453.6 g (1lb.) bag of rice is equal to 157 grains of rice.

What is weight?

The weight can be described as the force acting due to gravity. Weight can be considered as a vector quantity if the gravitational pull is acting on the body.

Therefore, in free fall, the weight of the object would be zero. Therefore, terrestrial objects can be weightless while ignoring air resistance.

The unit for measurement of weight is the same as of force, which is the newton. A body with a mass of 1 kilogram will exhibit a weight of about 9.8 Newton on the surface of the Earth, and about 1/6th as much weight on the Moon.

Given the weight of the 20 grains = 58 g

The weight of one grain = 58/20 = 2.9 g

The number of grains (n) of rice in weight 453.6 g of the bag of rice  can be calculated as:

n = 453.6/2.9

n = 156.4 ≈ 157

Therefore, the number of grains can be considered equal to 157 grains of rice.

Answers

Carbon Dioxide makes bubbles in the dough that make the bread fluffy. I think white break is the fluffiest.
Well it's simple, bread flour has an increased amount of protein or more gluten which results in a lighter, fluffier dough which produces a less dense finished product. All-purpose flour can be used for bread but bread flour is always better if your goal is a “fluffier” bread.

during a 2 hour trip,a family is able to travel 140 kilometers. what is the average speed of the family during this portion of this trip?

Answers

The average speed of the family : 70 km/h

Further explanation

Given

time = 2 hour

distance = 140 km

Required

The average speed

Solution

Distance is the length traveled by an object within a certain time  

Average speed = total distance/total amount of time

Can be formulated :

 Avg speed = d : t

Total distance traveled : 140 km

Total time : 2 hr

Avg speed = 140 : 2 = 70 km/h

Ideally speaking, bonds tend to form between two particles such that they are separated by a distance where _______ net force is exerted on them, and their overall energy is _________.

Answers

The question is incomplete, the complete question is;

Ideally speaking, bonds tend to form between two particles such that they are separated by a distance where _______ net force is exerted on them, and their overall energy is _________.

A.zero, maximized

B. a negative, minimized

C. a positive, minimized

D. a positive, maximized

E. zero, minimized

F. a negative, maximized

Answer:

E. zero, minimized

Explanation:

Chemical bonding occurs when there is a dynamic equilibrium between the attractive and repulsive forces. This means  that the magnitudes of the attractive and repulsive forces are equal and the net force is zero.

Also, at the point where bonding occurs, the energy of the system is minimum. The point on the potential energy curve that represents the bonding energy is the lowest point on the curve.

Ideally speaking, bonds tend to form between two particles such that they

are separated by a distance where zero net force is exerted on them, and

their overall energy is minimized.

For chemical bonding to occur there must be dynamic equilibrium. This is

formed from  magnitude of the attractive and repulsive forces being equal

which translates to the net force being zero.

The overall energy at the exact point of bonding is at the minimum which is

to allow easy transfer or sharing of electrons in the formation of a compound.

At a constant temperature, the gas volume is inversely proportional to the pressure applied  

[tex]\rm p_1V_1=p_2.V_2\\\\\dfrac{p_1}{p_2}=\dfrac{V_2}{V_1}[/tex]
