Hello,
In this case, based on the given, we can infer that as titanium is hot and water cold, it cools down whereas the water is heated up, therefore, in terms of heat, we have that the heat lost by the titanium is gained by the water:
That in terms of mass, specific heat and temperatures is:
In such a way, for computing the mass of titanium, considering the heat capacity of water 4.18 J/g°C, we have:

Na would form a 1+ ion losing its electron to the Cl to make a Cl- ion. Gives the molecule NaCl
Answer:
True
Explanation:
We want to find what 40° Celsius is equal to in Kelvin. The formula is below.
K= °C+ 273.15
Since we want to find Kelvin for 40° C, substitute 40 in for °C.
K= 40 +273.15
Add the two numbers together.
K= 313.15
The questions asks us if 40° C is equal to 313.150 K. Our answer is 313.15 K. Since 313.150 and 313.15 are equal, the answer is true.
I believe the answer is C, hydrogen bonds. A water molecule consist of two hydrogen atoms bonded to an oxygen atom, and a bent overall structure. Water molecules can only form hydrogen bonds between the partially positively charged hydrogen atoms in water molecules and a partially negatively charged atom in another molecules say oxygen in another water molecule.<span />
Answer:
Amount of water
The thermometer
Explanation
In an experiment, there is always a dependent variable and an independent variable. The independent variable is manipulated and its effect on the dependent variable is observed.
The control is that factor in the experiment that must remain constant so that effect of the independent variable on the dependent variable can be observed.
In this case, the independent variable is the amount of sodium chloride while the dependent variable is the temperature at which the solution boils.
The controls must be the amount of water which must be held constant and the same thermometer used to measure the temperature so that the effect of the amount of sodium chloride on the temperature of the solution can be studied.
