Answer:
Specific heat capacity is measured by determining how much heat energy is needed to raise one gram of a substance one degree Celsius. The specific heat capacity of water is 4.2 joules per gram per degree Celsius or 1 calorie per gram per degree Celsius
Explanation:
Answer:
139/56 Ba
Explanation:
In writing nuclear equations, there must be a balance of the mass and charge on both sides of the reaction equation. That is, the sum of masses on the lefthand side of the nuclear reaction equation must equal the sum of masses on the righthand side of the nuclear reaction equation. Similarly, the charges on the lefthand side of the nuclear reaction equation must equal the sum of the charges on the right hand side of the nuclear reaction equation.
Hence, the isotope of barium formed in the equation mentioned in the question is 139/56 Ba.
Answer:
Understanding the unit cell of a crystalline solid will help you in determining the empirical formula of the ionic solid compound because they both represent the smallest portion of the whole crystalline solid proportion.
Explanation:
A unit cell is the smallest portion of a crystal lattice, that can show the 3 dimensional pattern of the whole crystal.A formula unit is the lowest whole number ratio of ions in a an ionic compound.By considering the smallest repeating units/ unit cell, you can describe the structure of a crystalline solid.Knowing this can help in determining the empirical formula of the ionic solid compound.
The average rate of a reaction is a good approximation of an instantaneous rate when the concentration is measured during relatively brief time intervals.
At any point during such a little period, the average rate will be extremely near to the instantaneous rate. The average rate will differ from the instantaneous rates inside the period more when time intervals are longer.
The concentration change during a chosen time period is the average rate. When you take the measurements makes a difference.
The rate at a specific moment is known as the instantaneous rate. Finding the slope of the tangent to the concentration vs. time curve at that point yields the answer.
