F and O
because they are more reactive than Cl
If two gases with pressures of 2 atm and 3 atm are mixed at constant temperature, the total pressure will be the sum of the two pressures. Therefore the answer is D. 2 atm + 3 atm or 5 atm will be the total pressure of the gas mixture.
I believe the correct answer from the choices listed above is the third option. A ball falling through the air has <span>both potential energy because it still has a distance to move before it hits the ground and kinetic energy because it is moving. Hope this answers the question. Have a nice day.</span>
Answer:
99.3%
Explanation:
The percent by mass of the solute can be expressed as:
- % mass =
* 100%
And for this problem:
- Mass of Solute = Mass of sodium lithium chloride = 29 g
- Mass of Solvent = Mass of Water
So to calculate the percent by mass first we need to <u>calculate the mass of water</u>, to do so we use its<em> density</em> (1 g/L):
- 202 mL is equal to (202/1000) 0.202 L.
Density water = mass water / volume
- 1 g/L = mass water / 0.202 L
Now we have all the data required to <u>calculate the % mass:</u>
- % mass =
* 100 % = 99.3%
Making moral judgments or decisions is not a characteristic of science.
<h3>The scientific method</h3>
The scientific method refers to systematic methods employed by scientists in their quest for discoveries and explanation of phenomena.
The scientific method includes:
- Observation and formulation of questions
- Developing a hypothesis
- Conducting experiments
- Formulation of theories based on experiments
- Conducting further experiments and research
- Formulation of laws.
Thus, the characteristics of science include:
- relies on evidence
- uses testable ideas
- leads to ongoing research
Therefore, making moral judgments or decisions is not a characteristic of science.
