What is the difference between alkaline batteries and regular ones? Alkaline batteries have a higher energy density and a longer shelf life – the time a battery can remain in storage without losing any of its capacity. Lastly, the Alkaline cells have an Extra Power Formula to maintain power for a longer period in high-drain […]

Can noble gases exist alone in nature? In nature the atoms of noble gases do not bond either with other gases or with each other. Helium exists as atoms of Helium not as diatomic molecules. Some of the larger noble gases can be made to form molecules. This does not normally happen in natural conditions. […]

What solution Cannot dissolve any more solute? When a solution reaches the point where it cannot dissolve any more solute it is considered “saturated.” If a saturated solution loses some solvent, then solid crystals of the solute will start to form. What happens when solute mixed with solvent? When one substance dissolves into another, a […]

Why do we have 2 tides a day? This occurs because the moon revolves around the Earth in the same direction that the Earth is rotating on its axis. Since the Earth rotates through two tidal “bulges” every lunar day, we experience two high and two low tides every 24 hours and 50 minutes. What […]

Does the moon change your weight? Since the Moon is smaller than Earth, it has a weaker gravitational pull. In fact, the Moon only has 1/6 the gravity that Earth does. This means you weigh six times less on the Moon than you do on Earth! Can a person on Moon experience weight? yes, a […]

What is the end of a chain called? Bails. The part of the pendant that goes over the chain is called the bail or bale. This holds the piece to the chain. Most bails are attached to a metal pendant. What is chain speed? Chain speed, normally calculated in feet or metres per minute, is […]

What form of energy is causing a change in the frozen yogurt? Heat energy Which frozen yogurt is the healthiest? TCBY. With the highest number of live active cultures—aka probiotics, which offer numerous health benefits—included (seven different microbes!), this is the top pick among healthy frozen yogurts. Compared to other brands, TCBY boasted a higher […]

Explanation: Radio waves are electromagnetic waves with the longest wavelengths, lowest frequencies, and least amount of energy. What type of electromagnetic waves is used in cellular phone Brainly? Answer. Explanation: Mobile phones communicate […]

What is heat transfer absorptivity? Absorptivity (α) is a measure of how much of the radiation is absorbed by the body. Reflectivity (ρ) is a measure of how much is reflected, and transmissivity (τ) is a measure of how much passes through the object. Emissivity (ε) is a measure of how much thermal radiation a […]

What atom has an atomic number of 2? Helium What has the highest atomic number? Oganesson Which atom will more easily pull in the electrons? In particular, cesium (Cs) can give up its valence electron more easily than can lithium (Li). In fact, for the alkali metals (the elements in Group 1), the ease of […]
