How the concentration affects the rate of reaction? Concentration. If you increase the concentration of a reactant, there will be more of the chemical present. More reactant particles moving together allow more collisions to happen and so the reaction rate is increased. The higher the concentration of reactants, the faster the rate of a reaction […]
What are observable and measurable properties of matter?
What are observable and measurable properties of matter? Observable properties include measurements like height, weight, temperature, and the volume of an object. Explanation: Observable properties are things we can use our five senses to determine, the measurable properties in the question need a tool like a thermometer or a ruler to determine. What are the […]

Is it true that white blood cells prevent the loss of blood by causing clotting?
Is it true that white blood cells prevent the loss of blood by causing clotting? White blood cells—including neutrophils, monocytes, lymphocytes, eosinophils, and basophils—are involved in the immune response. Platelets form clots that prevent blood loss after injury.

What is the main cause of volcanic activity?
What is the main cause of volcanic activity? Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth’s mantle melts. If magma is thick, gas bubbles cannot easily escape and pressure builds up as the magma rises. When the pressure is too much an explosive eruption can happen, […]

When electrons are transferred between two atoms a covalent bond is formed?
When electrons are transferred between two atoms a covalent bond is formed? Covalent bonds and molecules A covalent bond is formed when two atoms share electron pairs. In a covalent bond, the stability of the bond comes from the shared electrostatic attraction between the two positively charged atomic nuclei and the shared, negatively charged electrons […]
